perfect theory?

Some people might think that in the future we will be able to produce a scientific theory that contains the answer of every single question. Consequently there would be no paradigm shift anymore. However I don't agree with them. The main reason for me to disagree is the current economical crisis. After the fall of the Soviet Union and therefore the fall of the communistic idea, we all started to live in the capitalistic paradigm. The theory behind the capitalistic system was perfect. And every student started to learn the basic capitalistic principals at school. In the last decade an Asian economist made an equation. This equation gave banks the ability to calculate how they could earn the highest amount of money. This equation worked until the beginning of the current crisis. The problem of the equation was very simple; it did not work in a time with decreasing house prices. That economist did not realised this mistake was very understandable. Because house prices simply didn’t decline after the Second World War. Now we say that the capitalistic system is dead, and that the state should have more control over our economy. This is really a paradigm shift in the economical world.

What I am trying to explain is that we might be able to make a theory which can solve every question. However there will be a moment were something will change. This change will change the world or universe. Consequently the theory does not work any more and it has to change.
